Plants grow upward from a tip of undifferentiated tissue called the shoot apical meristem. As the tip extends, stem cells at the center of the meristem divide and increase in numbers. But the cells on the periphery differentiate ...

(Phys.org)—Biologists have teamed up with mechanical engineers from the The University of Texas at Dallas to conduct cell research that provides information that may one day be used to engineer organs.

Atmospheric aerosol particles have a significant effect on climate. An international team of researchers has now discovered that a chemical process in the atmosphere called aging determines to a major extent ...

Oxygenic photosynthetic organisms utilize energy from the sun to split water into protons, electrons and oxygen—products vital to life on earth. The process takes place through light-induced electron transfer ...

Giant cells called "titan cells" protect the fungus Cryptococcus neoformans during infection, according to two University of Minnesota researchers. Kirsten Nielsen, Ph.D., an assistant professor in the department of microb ...

(PhysOrg.com) -- In the complex molecular mixer that is the atmosphere, some molecules dance with others and some are wallflowers, according to scientists at Pacific Northwest National Laboratory. Using a ...

Researchers at the University of Illinois at Chicago College of Medicine describe for the first time a key target of DNA damage checkpoint enzymes that must be chemically modified to enable stable maintenance of chromosome ...

(PhysOrg.com) -- Microfossils found in Australia show that more than 3.4 billion years ago, bacteria thrived on an Earth that had no oxygen, a finding that boosts hopes life has existed on Mars, a study published ...

A short-term treatment with three immune-dampening drugs allowed human embryonic stem cells to survive and thrive in mice, according to researchers at the Stanford University School of Medicine. Without such treatment, the ...

(PhysOrg.com) -- Researchers used a yeast model to map epigenetic processes-- those that influence gene expression -- in cells as they undergo sperm formation. Understanding the process can help explain how it goes awry ...

New research indicates that the interactions of microscopic organisms around a particular organic material may alter the chemical properties of the ocean and ultimately influence global climate by affecting ...

The sediments of the Kimmeridge Clay Formation were deposited during the Late Jurassic between around 160 and 145 million years ago, the age of the reptiles. They are the main oil source rock in the North ...

(PhysOrg.com) -- New research from scientists at The University of Manchester is set to improve predictions about climate and air quality - and make life easier for those suffering from respiratory problems.
